泰国海洋野生动物，安达曼海，水下洞穴中的扫帚鱼

o sweepers (Pempheris vanicolensis) pack the Fish Bowl chamber of The Chimney cavern system at Ko Haa in a dense school, their bronze flanks catching the limited ambient light as the smaller chamber entrance is visible beyond. A nocturnal species, the Vanikoro sweeper uses sheltered cavern environments as daytime refuge, making cavern dive sites like The Chimney among the most productive for observing this schooling behaviour. 4K, horizontal, wide angle, scuba diver POV.
